A Call for Accurate Language about CO2 in the AGW Discussion

In an otherwise fine article at WattsUpwithThat.com, Ari Halperin writes: For some time, the subject [of the residence time of anthropogenic carbon dioxide in the atmosphere] was surrounded by confusion, created by sloppy definitions and evasive statements in IPCC assessment reports. There was a mix-up between the residence time of a CO2 molecule in the

Preventing Climate Change does Not Help the Poor, It Dooms Them!

Many climate scientists argue that we need to mitigate global warming because otherwise it will be the poor who will be hurt the most. Apparently these scientists do not understand their own models. Projections from climate models are based on the rates of poverty reduction, with the highest (‘worst’) temperature projections resulting when the poorest

Does the “Precautionary Principle” Favor Fighting “Climate Change”?

Climate Scientists are Steadily Reducing Estimates of Warming from CO2

Among climate scientists specializing in climate sensitivity there is a clear trend toward lower and lower estimates of it, as the chart below shows. Why? Because the empirical measurements of GAT have fallen so much lower than model-generated predictions. In the chart, the dates are dates of publication (bottom axis) of peer-reviewed studies making estimates
